review-performance

Review Apache Pinot diffs for performance regressions in hot paths — per-row allocations, autoboxing, virtual dispatch in tight loops, large synchronized sections on the query path, unnecessary ByteBuffer copies, string concat in loops, and missing fast-paths for common types. Trigger keywords — TransformOperator, FilterOperator, ForwardIndexReader, segment scan, per-row, query hot path, allocation, autoboxing, JMH, benchmark.

review-process-scope

Review Apache Pinot diffs for process and scope discipline — PR size, single-concern commits, commit message clarity, referenced issues/PRs on reverts, anti-patterns like "add retry to fix flake", labels (backward-incompat), rolling-upgrade notes, and TODO hygiene. Trigger keywords — revert, retry, flake, TODO, backward-incompat, rolling upgrade, PR description.

review-testing

Review Apache Pinot diffs for test coverage and test quality — positive + negative cases, real dictionaries vs mocks, rolling-upgrade / mixed-version tests, null-handling toggle coverage, exhaustive type coverage for aggregators/operators, integration-test base-class choice (reject standalone clusters unless special setup is needed; prefer `CustomDataQueryClusterIntegrationTest`), assertion quality, and regression tests that reproduce the bug. Trigger keywords — Test, TestNG, JUnit, Mockito, mock, integration test, assertEquals, assertThrows, regression, null handling test, mixed version, CustomDataQueryClusterIntegrationTest, BaseClusterIntegrationTest.

fastexcel-to-fesod

Migrates a Java project from FastExcel 1.3 (cn.idev.excel:fastexcel:1.3.0) to Apache Fesod (org.apache.fesod:fesod-sheet:2.0.1-incubating). Invoke this skill when asked to "migrate FastExcel to Fesod", "upgrade to Apache Fesod", or "replace cn.idev.excel". FastExcel 1.3 is the direct predecessor of Apache Fesod. Supports both legacy namespaces seen in real projects: cn.idev.excel.* and org.apache.fesod.excel.*. The entry classes FastExcel and FastExcelFactory are kept as @Deprecated aliases in Fesod, so call-site renames are strongly recommended but NOT required for compilation. The only breaking change is the Java package prefix.

cua-driver

Drive a native macOS app via the cua-driver MCP server or CLI — snapshot its AX tree, click/type/scroll by element_index, verify via re-snapshot. Use when the user asks you to operate, drive, automate, or perform a GUI task in a real macOS application on the host (e.g. "open a file in TextEdit", "navigate to /Applications in Finder", "click the Save button in Numbers").

deepchat-data-import

Help developers build third-party tools that import, inspect, migrate, or analyze DeepChat data. Use when Codex needs to work with DeepChat provider configuration, model configuration, MCP/app settings, sessions, messages, legacy chat data, `agent.db`, `chat.db`, SQLCipher encrypted SQLite, Electron safeStorage wrapped passwords, Tauri importers, or native macOS/Windows/Linux data access.

deepchat-release

Prepare and publish DeepChat releases in this repository. Use when Codex needs to bump the app version, update CHANGELOG.md, keep release notes bilingual from v1.0.1 onward with English bullets first and Chinese bullets second, run release checks, create or update versioned release branches such as release/v1.0.1, continue a half-finished release, fast-forward main with the documented release flow, create or push version tags, or clean up release branches after publishing.

deepchat-sdd

Use before substantial DeepChat code, configuration, documentation, test, build, feature, issue, refactor, or architecture changes that need a durable spec. Skip trivial style fixes, small localized logic changes, routine docs edits, and simple bugs unless the developer asks for SDD. Classify substantial work into feature SDD, complex-bug issue spec, or architecture SDD; ask before optional GitHub issue sync unless the developer explicitly requested sync.
